THIS RESOURCE IS NO LONGER IN SERVICE, documented on February 08, 2013. A repository for physical mapping data of the human X chromosome that aims at providing a global view of genomic data at a chromosomal level including an integrated physical, genetic, transcript and sequence map of the human X chromosome. This implies acquiring, understanding and formatting an enormous amount of experimental results and can only be accomplished progressively. We have chosen to start the integration process with YAC maps generated by the community. These provide the basis for future higher resolution physical maps, as well as emerging transcript and sequence maps. The current content of IXDB therefore reflects this situation, with the emphasis placed on YAC mapping data. Due to their immediate value, IXDB has also started to systematically include bacterial clone contig maps and EST data. Currently IXDB does not store sequence data, although links to nucleic sequence databases are provided.

A language / data exchange format designed to describe and communicate information about microarray based experiments that is based on XML and can describe microarray designs, microarray manufacturing information, microarray experiment setup and execution information, gene expression data and data analysis results. MAGE-ML has been automatically derived from Microarray Gene Expression Object Model (MAGE-OM), which is developed and described using the Unified Modelling Language (UML) -- a standard language for describing object models. Descriptions using UML have an advantage over direct XML document type definitions (DTDs), in many respects. First they use graphical representation depicting the relationships between different entities in a way which is much easier to follow than DTDs. Second, the UML diagrams are primarily meant for humans, while DTDs are meant for computers. Therefore MAGE-OM should be considered as the primary model, and MAGE-ML will be explained by providing simplified fragments of MAGE-OM, rather then XML DTD or XML Schema. (from the description by Ugis Sarkans) The field of gene expression experiments has several distinct technologies that a standard must include. These include single vs. dual channel experiments, cDNA vs. oligonucleotides. Because of these different technologies and different types of gene expression experiments, it is not expected that all aspects of the standard will be used by all organizations. Given the massive amount of data associated with a single set of experiments, it is felt that Extensible Markup Language (XML) is the best way to describe the data. The use of a Document Type Definition (DTD) allows a well-defined tag set, a vocabulary, to describe the domain of gene expression experiments. It also has the virtue of compressing very well so that files in an XML format compress to ten percent of their original size. XML is now widely accepted as a data exchange format across multiple platforms.
THIS RESOURCE IS NO LONGER IN SERVICE, documented July 6, 2016. This blog, which is maintained under the aegis of the Concept Web Alliance, is devoted to the Concept Web a dynamic, interactive fabric of concepts and their relationships. The Concept Web is constructed from, inter alia, research literature, Internet databases and other web sites together with off-line resources. The aim of creating the Concept Web is to remove both redundancy and ambiguity from available knowledge in order to help deal with information overload, to semantically "connect" concepts, and so to maximize the potential for knowledge discovery.
THIS RESOURCE IS NO LONGER IN SERVICE, documented on July 17, 2013. The Neuroscience Mutagenesis Facility of the Jackson Laboratory (NMF) was established to produce new neurological mouse models that could serve as experimental models for the exploration of basic neurobiological mechanisms and diseases. The protocols are available. The impetus for the program resulted from the recognition that * the value of genomic data would remain limited unless more information about the functionality of its individual components became available, and * the task of linking genes to specific behavior would best be accomplished by employing a combination of different approaches. In an effort to complement already existing programs, the Neuroscience Mutagenesis Facility decided to use: a random, genome-wide approach to mutagenesis, i.e. N-ethyl-N-nitrosourea (ENU) as the mutagen; a three-generation back-cross breeding scheme to focus on the detection of recessive mutations; behavioral screens selective for the detection of phenotypes deemed useful for the program goals. Protocols: * Genetics ** Production of Mice for a Genome-Wide ENU Mutagenesis Screen ** Production of Mice using Chemical Mutagenesis of Mouse ES Cells * Protocols ** Step by step procedures-- Mouse mutagenesis with ENU ** Step by step procedures-- ES Cell mutagenesis with EMS * Phenotyping: Overview * Protocols:(currently only screens marked * are in use) ** Acoustic startle response (ASR) ** Auditory brainstem response (ABR) ** CLAMSTM(former CCMS) ** Creatine kinase ** Developmental Screen * ** Eye and Vision * ** Gait Analysis ** Gustation ** Observation * ** Seizure threshold * ** Additional Background Information
Database of a list of insertion sequences isolated from eubacteria and archaea. It is organized into individual files containing their general features (name, size, origin, family.....) as well as their DNA and potential protein sequences. Although most of the entries have been identified as individual elements, a growing number are included from their description in sequenced bacterial genomes. The search engine permits the retrieval and display of individual and groups of ISs based on a combination of their general features. Two levels of search are available. The simple search option enables the user to sort elements using a limited number of basic items whereas the extensive search offers an additional set of possibilities such as comparisons of the sequences of terminal inverted repeats and a variety of different layout displays. Built in links are provided to: the EMBL sequence database, the NCBI taxonomy database and to the ESF plasmid database. At present, only individual sequences can be downloaded one by one for comparison. An on-line BLAST facility is available and in future versions direct access to additional analytical tools will be provided on line. Direct submission of ISs is encouraged using the on-line form provided.

A community-driven knowledgebase of Alzheimer disease, in which researchers can annotate scientific claims, data, and information, putting these into the context of testable hypotheses and treatment discovery. This SWAN project adds a collection of hand-curated hypotheses to a research paper, which are then related through a set of discourse relationships. They can be browsed and relations between claims, as well as support networks for a specific claim, are made and visualized. AlzSWAN is where you explore scientific knowledge about Alzheimer disease and share your own ideas, comments and questions in a semantically structured system. AlzSWAN is enabled by Semantic Web technology, a new standard for knowledge organization and transfer on the Web. AlzSWAN organizes and manages knowledge using formal knowledge descriptions called ontologies. Using these formal knowledge descriptions, they can tie statements made in scientific publications or on the Web to scientific evidence, biological terminologies, and knowledgebases, and to claims and counterclaims made by other researchers.

Documented on January 4, 2023.Consortium that developed brief, standardized and reliable procedures for the evaluation and diagnosis of patients with Alzheimer's disease (AD) and other dementias of the elderly. These procedures included data forms, flipbooks, guidebooks, brochures, instruction manuals and demonstration tapes, which are now available for purchase. The CERAD assessment material can be used for research purposes as well as for patient care. CERAD has developed several basic standardized instruments, each consisting of brief forms designed to gather data on normal persons as well as on cognitively impaired or behaviorally disturbed individuals. Such data permit the identification of dementia based on clinical, neuropsychological, behavioral or neuropathological criteria. Staff at participating CERAD sites were trained and certified to administer the assessment instruments and to evaluate the subjects enrolled in the study. Cases and controls were evaluated at entry and annually thereafter including (when possible) autopsy examination of the brain to track the natural progression of AD and to obtain neuropathological confirmation of the clinical diagnosis. The CERAD database has become a major resource for research in Alzheimer's disease. It contains longitudinal data for periods as long as seven years on the natural progression of the disorder as well as information on clinical and neuropsychological changes and neuropathological manifestations., THIS RESOURCE IS NO LONGER IN SERVICE.
